This project will involve the study of nuclear reactions primarily utilizing unstable nuclei, i.e. radioactive nuclear beams (RNBs). It will also involve the development of new types of instrumentation, techniques and apparatus to facilitate these studies. The latter will include the development and utilization of special superconducting-magnet ion-optical systems together with detector systems optimized for nuclear-reaction studies involving short-lived nuclear beams such as Lithium-8, Helium-6 and metastable ions (Fluorine 18-m). Specific experiments will include studies related to nuclear astrophysics (the synthesis of elements in stars, the solar-neutrino and missing-mass problems, supernova and the Big Bang), and the special structure of very neutron-rich and proton-rich nuclei (Lithium-8, Helium-6,...). The work will involve both graduate and undergraduate students from the University of Michigan and elsewhere and faculty members from several institutions. The work will exploit the unique capabilities of the new double-solenoid RNB apparatus recently installed at the University of Notre Dame accelerator as part of a joint UM-UND project. Additional research will be done at the nearby National Superconducting Cyclotron Laboratory at Michigan State University.

该项目将涉及主要利用不稳定原子核（即放射性核束（RNB））的核反应研究。 它还将涉及新型仪器、技术和设备的开发，以促进这些研究。 后者将包括开发和利用特殊的超导磁体离子光学系统以及针对涉及短寿命核束（例如锂8、氦6和亚稳态离子（氟18-m））的核反应研究而优化的探测器系统。 具体实验将包括与核天体物理学（恒星中元素的合成、太阳中微子和质量缺失问题、超新星和大爆炸）以及富含中子和富含质子的原子核（锂8、氦6等）的特殊结构相关的研究。 这项工作将涉及密歇根大学和其他地方的研究生和本科生以及来自多个机构的教职人员。 这项工作将利用最近安装在圣母大学加速器上的新型双螺线管 RNB 装置的独特功能，作为 UM-UND 联合项目的一部分。 其他研究将在附近的密歇根州立大学国家超导回旋加速器实验室进行。
